So I am getting differing opinions as to when the 20% rule kicks in. I have got a remodel project where a conference room is being remodeled to accommodate additional staff. It is my understanding that the cost of this, which includes an ADA bathroom, does not count towards the 20% additional that must be spent for ADA mitigation since it must be constructed to ADA standards anyway. There are two additional non-ADA public restrooms that can be remodeled to meet ADA requirements. If these two restrooms are remodeled it is my opinion that the cost would be applied to the 20% requirement. I should add that the architect has indicated that he has done numerous projects and this is the first time the 20% rule has been brought up. Estimated cost of remodel is $200,000.00.
